#Continuous variables are presented as median and IQR and categorical variables as number (n) and percentage; N represents the total number of patients for whom data were available for that particular variable; IGSI: index gallstone ileus; RGSI: recurrent gallstone ileus; ISOI: site of impaction in index gallstone ileus; RSOI: site of impaction in RGSI; categorical variables were examined by the chi-square test and continuous variables by the Kruskal–Wallis test.
